Astaxanthin reduces eye fatigue
Several randomized double blind placebo controlled studies conducted in Japan have shown promising results. These unpleasant symptoms are reduced after 4 weeks of supplementing astaxanthin
For example, a study by Nagaki et al (2002) demonstrated that after 5 months of supplementing astaxanthin 54% of subjects reported reduced subjective symptoms of eye strain: fatigue, dryness, blurred vision (n=26). The placebo group did not display any change (n=13)1. The reduction of eye strain after supplementing astaxanthin has been attested not only by personal observations of the subjects, but also through objective measurements. For example, in a study by Nitta et al (n=30) after 4 weeks of supplementing astaxanthin (6mg and 12mg per day) accommodation amplitude improved.1 2 3 4 6 7. Other studies have obtained similar result3 4 5 6 7.

Astaxanthin improves capillary circulation in the eyes
Low antioxidant levels and reduced blood flow are the main reasons that can cause disruption of capillary circulation. Circulation in the retina is the very foundation of the internal balance in the eye. Good circulation ensures that the eye is properly supplied with oxygen, waste products are removed and the eye receives nutrients.
After 4 weeks of supplementing astaxanthin (6mg per day) the blood antioxidant level increased significantly and capillary circulation improved in both eyes (n=18). The placebo group showed no change (n=18)8.

Astaxanthin reduces inflammation in the eyes in vitro and in vivo.
Two studies came to the same conclusion – astaxanthin displays anti-inflammatory effects in the iris of the eye – the ciliary muscle. Astaxanthin suppressed free radical induced activation of NF-kB, which causes and amplifies inflammation. The result was a lower pro-inflammatory response9. Another study demonstrated the anti-inflammatory properties of astaxanthin in endotoxin-induced uveitis10. The researchers explained that astaxanthin’s ability to reduce the number of inflamed cells in the iris is one of the reasons why it alleviates symptoms of eye fatigue.

Astaxanthin delays onset of presbyopia
Therefore, the researchers concluded that astaxanthin may slow down the progression of presbyopia in middle-aged and elderly people11.
In another study volunteers were given different doses of astaxanthin (0 mg, 2 mg, 4 mg and 12 mg per day). After ingestion of astaxanthin for 28 consecutive days, the uncorrected far visual acuity significantly improved in groups receiving 4 mg and 12 mg doses. Statistically viable improvement was also documented for accommodation amplitude/speed (refocusing from near to far objects and vice versa)12.

For healthy, beautiful, age defying skin
Natural astaxanthin, which is obtained from freshwater microalgae, is the most powerful antioxidant known to science. It is deemed to be the most powerful agent in the anti-aging industry, which is worth billions, it is incorporated into many prestigious anti-aging products and recommended by leading skincare specialists.
Clinical research shows that natural astaxanthin significantly improves all layers of skin by protecting them against their main enemy – free radicals. The result is improved health of the skin; its natural beauty and radiance is revealed. Scientific evidence has been found explaining why astaxanthin significantly reduces wrinkles. The secret is astaxanthin’s ability to stimulate regeneration of collagen fibres. Collagen tissue ensures skin strength and elasticity, gives it a youthful and smooth appearance. The fine weave of collagen fibres is damaged by UV radiation and the massive production of free radicals that it induces. Astaxanthin reduces the effects of reactive oxygen molecules, thus allowing collagen to maintain its ability to regenerate.
Clinical benefits of natural astaxanthin:
Revitalises photoaged skin by quenching oxidative stress and inflammation in all skin layers
Reduces age spots by quenching overproduction and oxidation of melanin
Reduces the size of wrinkles and improves skin microtexture
Improves elasticity in the skin by strengthening the collagen layer
Vision and eye health
Any tissue that is subjected to light is affected by UV radiation and the photooxidative damage it causes; the retina is especially vulnerable as it contains many polyunsaturated fatty acids. UV damage is the main cause of two of the most common diseases leading to impaired vision and blindness – age-related macular degeneration and age-related nuclear cataract.
Antioxidants fight adverse processes, however, the eye contains only a couple of antioxidants – those that can penetrate the fine blood-retinal barrier, and astaxanthin is one of them. The result – less free radicals are formed due to UV glare and eye inflammation inducers are activated less. This is beneficial not only for the elderly, whose eyes have already seen so much in this life, but also for all the computer users out there.
Clinical studies have found natural astaxanthin to improve eye health and vision by:
- improving blood circulation in the fine blood vessels in the eye (capillary circulation);
- relieving symptoms of Computer Vision Syndrome and eye fatigue;
- improving the eye’s ability and speed to focus on objects at various distances;
- reducing inflammation of the eye’s internal or ciliary muscle.
Physical endurance and fat metabolism
Natural astaxanthin improves endurance during physical activity by improving aerobic power. It is a powerful antioxidant and also has anti-inflammatory effects. Studies have found that supplementing astaxanthin can reduce lactic acid build-up, delay fatigue and reduce muscle atrophy in seniors.
Benefits of astaxanthin for muscle performance:
- Boosts muscle endurance and recovery
- Lowers lactic acid and fatigue
- Reduces muscle damage and inflammation
- Improves blood flow and the quality of red blood cells
- Enhances fat metabolism by improving mitochondria function
Benefits of astaxanthin for cardiovascular health:
- Improves blood lipid profiles
- Reduces oxidative stress
- Enhances capillary circulation
Natural astaxanthin protects the immune system against free radicals, thus maintaining its ability to function properly. It balances and strengthens the immune system at the same time. It enhances the body’s defences, whilst also helping to supress the overactive immune responses that create unwanted inflammation.
Benefits of natural astaxanthin for the immune system:
- Faster immune response
- Strengthens and balances the immune system
- Enhances production of antibodies
- Protects immune cells against oxidative stress
Benefits of natural astaxanthin for brain health:
- Reduces age-related forgetfulness, improves alertness and multitasking
- Decreases oxidation of red blood cells, which is linked to prevention of dementia
- Enhances capillary circulation and blood antioxidant quality
- Modulates blood pressure lowering the risk of stroke and improves vascular endothelial health
Benefits of natural astaxanthin for stomach health:
- Lowers gastric inflammation
- Decreases infection of H.pylori
- Reduces clinical symptoms in dyspepsia patients
